AWE Exhaust Suite – BMW M3 (F80) / M4 (F82/F83)
AWE's second-generation cat-back for the S55-powered M3 and M4 starts after the secondary catalysts and runs 76mm (3") and 64mm (2.5") T304L stainless steel. A precision X-pipe smooths out the S55's rasp, and a choice of rear section sets the character. AWE measured up to 8.9 kW (12 hp) and 21.7 Nm (16 ft-lb) at the wheels on its dyno.

Two versions are offered, each with quad 102mm (4") tips in chrome silver or diamond black. SwitchPath is valved: it uses the factory valve motors and keeps the M button and drive-mode control, close to stock at a cruise with the valves shut and loud with them open. Track Edition drops the valved muffler for a constant "valves open" sound, saves 10.2 kg (22.5 lb), and comes with AWE machined valve simulators for the factory valve motors.
Note: One design suits both OPF (Euro-spec) and non-OPF cars; AWE confirms 2015–2020 build years. All catalysts stay in place. Fitting requires cutting the factory pipes at the points marked in AWE's guide. Track Edition is loud, especially in Sport+. Installation by a professional is recommended.
